Abstract
A starting device of a gas turbine is used for starting the gas turbine and comprises stators and a rotor rotating relative to the stators. The rotor comprises a rotating shaft and a permanent magnet fixed to the rotating shaft. The rotating shaft of the rotor is fixedly connected with a main shaft of the gas turbine so that the rotating shaft and the main shaft can coaxially rotate. The stators surround the rotating shaft and can move relative to the axial direction of the rotating shaft. In the process of starting the gas turbine, the stators are located at the position exactly facing the rotating shaft in the radial direction. After the rotating speed of the main shaft of the gas turbine exceeds a preset rotating speed, the stators move axially to the position out of the radial direction range of the rotating shaft.

Specific embodiment
Before describing the embodiments in more detail it should be understood that the invention is not restricted in the application institute hereafter or in accompanying drawing
The detailed construction of description or arrangement of elements.The embodiment that the present invention can realize for alternate manner.Furthermore, it is to be understood that this paper institute
The wording using and term are solely for describing purposes, should not being construed as limiting property explain." inclusion " used herein, "comprising",
The similar wording such as " having " means and comprises items listed thereafter, its equivalent and other additional things.Particularly, work as description
When " certain element ", the present invention does not limit the quantity of this element as one it is also possible to include multiple.
Fig. 1 is rough schematic view when gas turbine starter starts.As shown in figure 1, described gas turbine includes opening
Dynamic device 10, combustor 11, gas turbine main shaft 12 and the compressor 14 being fixedly connected with gas turbine main shaft 12 and turbine
16.Wherein, starter 10 is connected to drive described gas turbine operating with gas turbine main shaft 12, and combustor 11 is connected to pressure
Between mechanism of qi 14 and turbine 16.
Starter 10 includes stator 18 and the rotor 20 rotating with respect to stator 18.Rotor 20 includes rotating shaft 22 and consolidates
The fixed permanent magnet 24 to rotating shaft 22, rotating shaft 22 directly is driven to be connected with gas turbine main shaft 12 and is enable rotating shaft 22 and gas turbine
Main shaft 12 coaxial rotating.
In the present embodiment, the rotating shaft 22 of rotor 20 is as a part and the gas turbine main shaft 12 of gas turbine main shaft 12
It is integrally formed.For example, in one embodiment, the rotating shaft 22 of rotor 20 integratedly extends from described gas turbine main shaft 12 and projects
End face in compressor 14.
In other embodiments, the rotating shaft 22 of rotor 20 can be the individual component being fixedly attached to gas turbine main shaft 12,
The mode that rotating shaft 22 directly drives combination with gas turbine main shaft 12 is taken to be connected.
In an illustrated embodiment, the rotating shaft 22 of stator 18 surrounding rotor 20 is installed and is arranged to respect to rotating shaft 22
Axial movement, specifically, in described gas turbine start-up course, stator 18 be located at rotating shaft 22 diametrically just to position
Put；After main shaft 12 rotating speed of described gas turbine is more than a desired speed, stator 18 moves axially to the radial direction model of rotating shaft 22
Outside enclosing, so, when described gas turbine drives rotating shaft 22 to rotate, because rotor 20 and stator 18 are spaced, rotor 20 is forever
Electromagnetic induction will not be produced, thus without generation magnetic resistance between the coil of magnet 24 and stator 18.
It should be noted that above-mentioned desired speed in the present embodiment be described gas turbine self-sustain speed, that is, without
